Thanks for that. You must dream in hex, as I did 2 decades
ago. Alas, all I dream about now is staying alive.
Simple XORing. Who would have guessed?
Too hard for me to figure out without your help. I will now
write a little program in free Pascal or maybe 16 bit assembler to
automate the process, unless you can recommend freeware (no online
datamining stuff) that does it automatically ?
